The NIT WDR Intensified modules are the first intensified Night Vision cameras with a very Wide Dynamic Range of more than 140dB.
The NIT WDR intensified cameras use the same principle as conventional ICCD/ICMOS technologies :
An image intensified is coupled to an image sensor via a straight optical fiber. When operating under low light conditions, each photon is multiplied by the intensifier tube and then collected by the HDR CMOS sensor.
Using the native HDR capabilities of our sensors brings high performances and overcomes three main limitations of traditional intensified solutions :
Dynamic Range: The high intra scene dynamic range eases the identification of targets whatever the light conditions.
No Blooming: Thanks to its unique feature, the WDR sensors offer clear images and details even when facing to intense light spots.
MTF : The 1 inch optical size of the WDR sensor (18mm) guarantees a use of a straight optical fiber (no taper needed). The WDR NIT sensors integrates a “Black Matrix” feature which reduces drastically the pixel crosstalk and ensures an optimal images sharpness.
